SUPPRESSION OF NOXIOUS FUMES FROM HIGH CALORIFIC FUELS CONTAINING S,CL,F

摘要

A method of cleaning reaction products which result from flame combustion of high calorific value fuels containing impurities such as sulphur, chlorine and fluorine compounds by the addition of additives binding the impurities in the combustion chamber. The additives are added to the fuel or the combustion air to provide the required degree of mixing, and the temperature of the flame is reduced to that required for effective reaction of the additives by introducing a stream of heat absorbing material into the combustion zone 6. The heat absorbing material can be recirculated exhaust gas.
